The air outlet cover 511 is further provided with a sterilizing and purifying chamber 54, and the sterilizing and purifying chamber 54 is arranged in parallel with the air outlet chamber 53 and both are positioned above the inner chamber 510. The sterilization and purification chamber 54 has a vertical side wall 532 shared with the air outlet chamber 53, the vertical side wall 532 is provided with an air inlet 533, and the bottom wall of the sterilization and purification chamber 54 is provided with an air outlet 541 communicated with the inner cavity.
Further, a rotation shaft 550 extending vertically and a partition 55 are fixed in the sterilization and purification chamber 54, the partition 55 is connected to the rotation shaft 550 and is rotatable about the rotation shaft 550, and an ozone generator 56 and a heating device 57 for heating gas are respectively installed on the partition 55. In this embodiment, the sterilizing and purifying chamber 54 is square, the partition 55 is a square plate, the rotating shaft 550 is fixed to the middle of the partition 55, and the ozone generator 56 and the heating device 57 are respectively fixed to both sides of the partition 55. In addition, the left and right sides of the partition 55 are respectively provided with an air inlet valve plate 58 capable of closing the air inlet 533, while the bottom of the partition 55 is provided with an air outlet valve plate 59 capable of closing the air outlet 541, the rotating shaft 550 passes through the middle of the air outlet valve plate 59, and the air outlet valve plates 59 at both sides of the rotating shaft 550 can both block the air outlet 541. A motor 551 for driving the rotation shaft 550 to rotate is provided at the top of the partition 55, and the ozone generator 56 and the heating device 57 are rotated along with the partition 55 by the motor 551.
The partition 55 divides the inner cavity of the sterilization and decontamination chamber 54 into two cavities by rotational energy, and has at least three states: in the first state, one of the air outlet valve plates 59 closes the air inlet 533, and the other air outlet valve plate abuts against the inner wall of the sterilizing and purifying chamber 54, so that the ozone generator 56 and the heating device 57 are respectively located in a closed cavity; the cooking state of the range hood (the air outlet 532 is opened at this time), and therefore, the ozone generator 56 and the heating device 57 are respectively in a closed cavity in the state, so that the pollution and damage of the oil smoke to the ozone generator 56 and the heating device 57 in the operation process of the range hood can be avoided.
In the second state, the two air outlet valve plates 59 respectively abut against the inner wall of the sterilizing and purifying chamber 54, the heating device 57 is in a closed cavity, and the ozone generator 56, the air inlet 533 and the air outlet 541 are in the same cavity, i.e. the range hood is in a sterilizing and deodorizing state at this time (at this time, the air outlet 532 is closed by the air outlet valve plates). The ozone generator 56 starts to operate, the fan 52 is in a low-speed operation state (i.e. the rotating speed of the fan is lower than that of the cooking state), air flow generated by the fan 52 enters the cavity where the ozone generator 56 is located through the air inlet 533, ozone generated by the ozone generator 56 enters the cavity 510 through the air outlet 541 under the action of the air flow, and as the air outlet 541 is located above the air inlet 521 of the fan 52, the ozone can quickly enter the fan 52 after being dispersed in the cavity 510 under the action of the air flow, and is led into the air outlet 53 through the rotation of the fan 52 after being dispersed in the cavity of the fan 52, so that dynamic circulation is formed in the sterilizing and purifying cavity 54, the cavity 510, the cavity of the fan 52 and the air outlet 53, and the concentration of the ozone reaches dynamic balance in the range hood. The ozone can not be automatically dispersed under the action of no external force because the specific gravity of the ozone is greater than that of the air, and the air flow generated by the fan 52 is introduced by the air inlet 533, so that the ozone can be effectively dispersed and flowed, the ozone can be uniformly distributed in all parts of the interior of the range hood, the ozone concentration in all parts of the interior of the range hood is uniform, the ozone in all parts of the interior of the range hood can be timely supplied under the action of the air flow, the concentration non-uniformity caused by the automatic decomposition of the ozone is avoided, the ozone concentration can be dynamically balanced in the whole sterilization and deodorization process, and the treatment effect of the ozone on the interior of the range hood is ensured.

The heating device 57 starts to operate, and the cavity in which the heating device 57 is positioned is quickly heated, so that ozone in the cavity is quickly decomposed. Meanwhile, the fan 52 keeps in a low-speed operation state, so that the heated hot air can be quickly led into the inner cavity 510 through the air outlet 541 by the air flow generated by the fan 52, and after being dispersed in the inner cavity 510, the hot air is led into the inner cavity of the fan 52 and is led into the air outlet cavity 53 under the rotation of the fan 52, so that the hot air forms circulation in the sterilizing and purifying chamber 54, the inner cavity 510, the inner cavity of the fan 52 and the air outlet cavity 53, the heating decomposition of ozone in the range hood can be quickened, and the hot air can be filled in the range hood, so that the range hood is in a dry state, and bacterial breeding is effectively avoided. The above heating device 57 can be implemented in various ways, and in this embodiment, the heating device 57 is a heating tube.
In this embodiment, in order to make the air inlet valve plate 58 close the air inlet 533 better, so as to effectively avoid the range hood from entering the sterilizing and purifying chamber 54 in the cooking state, an elastic reset assembly 50 is disposed between each air inlet valve plate 58 and the partition 55, and the elastic reset assembly 50 can make the air inlet valve plate 58 have a tendency to keep against the air inlet 533. Specifically, the cross section of each air intake valve plate 58 is arc-shaped, the two sides of the partition 55 are respectively fixed with a mounting frame extending along the height direction of the partition 55, each mounting frame comprises a mounting plate 553 perpendicular to the partition 55 and a limiting stop strip 552 fixed on the mounting plate 553 and perpendicular to the mounting plate 553, each air intake valve plate 58 is arranged opposite to the corresponding mounting plate 553, and the limiting stop strip 552 is positioned between the air intake valve plate 58 and the mounting plate 553.
